Product details

Overview

VNS1NV04DPTR-E from STMicroelectronics is a dual-channel, fully autoprotected high-side power switch IC built on VIPower™ M0-3 technology, integrating two OMNIFET II monolithic chips in a single SO-8 package. It delivers 1.7 A typical current limiting per channel, 250 mΩ R_DS(on) at V_IN = 5 V and T_j = 25 °C, and 40 V drain-source clamp voltage - enabling robust DC–50 kHz switching in automotive body control modules and industrial PLC output stages.

For engineers reviewing the VNS1NV04DPTR-E datasheet, VNS1NV04DPTR-E pinout, VNS1NV04DPTR-E application, or VNS1NV04DPTR-E equivalent, this device is selected for high-reliability load switching where integrated thermal shutdown, linear current limitation, diagnostic feedback via input pin, and ESD-hardened (4 kV HBM) operation are mandatory design requirements.

Technical Context

The device implements dual independent high-side switches with direct gate access for analog driving, each featuring autonomous protection circuitry: overvoltage clamp (40–55 V), linear current limiter (1.7–3.5 A), and junction temperature sensing (shutdown at 150–200 °C). Fault status is communicated through sink current (10–20 mA) on the INPUT pin without requiring external components.

Its SO-8 package supports dual-channel integration while maintaining compatibility with standard power MOSFET drive circuits. The internal low-impedance gate path enables TTL-level input compatibility, and the 100–150 µA supply current drawn from the input pin powers all protection logic without auxiliary bias rails.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	250 mΩ max per channel at V_IN = 5 V, I_D = 0.5 A, T_j = 25 °C - ensures low conduction loss in 12 V automotive loads up to ~1.5 A continuous.
Current limit (I_LIM)	1.7 A typical per channel at V_IN = 5 V, V_DS = 13 V - provides predictable short-circuit energy limiting without external sense resistors.
Drain-source clamp voltage (V_CLAMP)	40 V min at I_D = 0.5 A - protects against inductive kickback in solenoid/relay drivers without external TVS diodes.
Thermal shutdown threshold (T_jsh)	150–200 °C - triggers automatic cut-off before silicon damage; reset occurs at ~135 °C, enabling self-recovery after fault clearance.
Fault sink current (I_gf)	10–20 mA at T_j = T_jsh - delivers unambiguous diagnostic signal to microcontroller GPIO without level-shifting or amplification.
Input supply current (I_ISS)	100–150 µA at V_IN = 5 V - enables direct connection to low-power MCU outputs without loading concerns.
ESD rating (HBM)	4000 V - meets automotive-grade robustness requirements for under-hood and chassis-mounted control units.

Pinout & Package

SO-8 surface-mount package (ECOPACK® compliant, JEDEC MS-012AC); 1.75 mm max height; 5.0 mm × 6.2 mm footprint; thermal resistance junction-to-lead = 30 °C/W per channel.

Pin/Terminal	Circuit Role	Design Meaning
1 (INPUT1)	Channel 1 gate control & fault feedback node	Accepts TTL/CMOS logic or analog voltage; sinks 10–20 mA during thermal fault to signal MCU; draws only 100–150 µA in normal operation.
2 (SOURCE1)	Channel 1 source reference	Internally tied to GND; serves as return path for load current and diagnostic current; not isolated from substrate.
3 (DRAIN1)	Channel 1 high-side switched output	Connects to positive rail side of load (e.g., lamp, solenoid); clamped to ≤55 V during inductive turn-off.
4 (DRAIN2)	Channel 2 high-side switched output	Independent high-side output identical to DRAIN1; enables dual-load control with shared ground and separate inputs.
5 (SOURCE2)	Channel 2 source reference	Shared with SOURCE1 - both channels use common ground reference; no isolation between channels.
6 (INPUT2)	Channel 2 gate control & fault feedback node	Functionally identical to INPUT1; allows independent control and fault reporting for second channel.
7, 8 (GND)	Power and signal ground	Common ground for both channels and internal protection circuitry; must be low-impedance PCB plane for thermal and noise integrity.

Key Features

Feature	Design Value
Integrated linear current limiter	Stabilizes output current at 1.7 A typical during overload, eliminating need for external current-sense amplifier and comparator loop.
Thermal shutdown with auto-restart	Detects junction temperature >150 °C and disables channel; resumes operation when T_j drops to ~135 °C - avoids manual reset in embedded systems.
Overvoltage clamp with rugged avalanche capability	Clamps V_DS to 40–55 V during inductive switching, absorbing up to 55 mJ single-pulse avalanche energy - replaces discrete clamp diode in relay/solenoid drivers.
Diagnostic feedback via input pin	Provides active-low fault signaling (via 10–20 mA sink) directly on control line - eliminates dedicated fault pin and reduces MCU GPIO count.
TTL-compatible input interface	Operates with 0.5–2.5 V input threshold and draws only 150 µA - interfaces directly with 3.3 V or 5 V MCUs without level shifters or pull-up resistors.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side power switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STSPIN250	Single-channel, 2.6 A rated, integrated current regulation with SPI interface; requires external clock and configuration registers.	Targeted at motion control with closed-loop current tuning; lacks analog input compatibility and diagnostic sink current.	Select when programmable current profiles and multi-axis synchronization are required - not drop-in for simple on/off replacement.
TPS27082L	Single-channel, 2.8 A rated, 120 mΩ R_DS(on), but no integrated overvoltage clamp or linear current limiting - relies on external TVS and sense resistor.	Designed for space-constrained consumer electronics; lacks automotive-grade ESD (only 2 kV HBM) and thermal auto-restart.	Choose for cost-sensitive, non-automotive applications where board area is critical and external protection is acceptable.

Compared with STSPIN250 and TPS27082L, the VNS1NV04DPTR-E uniquely combines dual-channel integration, analog-input simplicity, autonomous clamp/current/thermal protection, and diagnostic feedback in one SO-8 package - making it optimal for automotive and industrial applications demanding functional safety without firmware overhead.

FAQ

Can VNS1NV04DPTR-E drive inductive loads without external flyback diodes?

Yes - its integrated overvoltage clamp (40–55 V) and 55 mJ single-pulse avalanche energy rating allow safe switching of relays, solenoids, and small DC motors without external flyback diodes. The clamp activates automatically during inductive turn-off, limiting V_DS to protect the die. However, for repetitive high-energy loads, external snubbers may still be recommended to extend lifetime.

What is the maximum continuous current per channel at 85 °C ambient?

At T_a = 85 °C with standard SO-8 PCB layout (58 mm × 58 mm, 2 oz Cu), thermal resistance junction-to-ambient is ~55 °C/W. With 4 W total dissipation limit and derating, maximum continuous current per channel is ~1.1 A (based on R_DS(on) increase to ~350 mΩ at T_j = 125 °C and power budget of 2 W/channel).

How does the diagnostic feedback work during thermal shutdown?

When junction temperature exceeds 150–200 °C, the device sinks 10–20 mA through the INPUT pin. If driven by a low-impedance source (e.g., MCU GPIO with <1 kΩ series resistance), this pulls the input voltage near 0 V, signaling fault. If the driver impedance is high, the pin voltage collapses - detectable as loss of logic high - without affecting recovery behavior.

Is VNS1NV04DPTR-E pin-compatible with earlier VNS1NV04DP-E?

Yes - both share identical SO-8 pinout, electrical specifications, and thermal characteristics. The "TR" suffix denotes tape-and-reel packaging only; no functional or parametric differences exist. Migration requires no PCB or firmware changes - only updated procurement and reel-handling logistics.
